I've just had an annoying problem with Kmail2 (Mint KDE crashed, so I re-installed, but couldn't get Kmail2 to import/recognise the old emails - even though it was the same software version!). I've been looking at Thunderbird, but really wanted something based on QT toolkit, so this looks good!

Seems like a very fast way to access mails. Dont expect any advanced features. More from Project's wiki:

What Trojitá is not:

A full PIM suite. That's something which we leave to other applications, so you won't find a fully fledged calendar in Trojitá. But you might help us make Trojitá a part of a fully-fledged PIM if you're interested. A POP3 client. Trojitá works by accessing a remote mail store over the IMAP protocol. POP3 cannot work this way for technical reasons. Finished yet. If you try Trojitá yourself, you will notice that some "obvious" features are missing. We are working on getting them fixed, but we could definitely use a help.

Some highlights of Trojitá are:

A pure Qt4 (and Qt5!) application with no additional dependencies Robust IMAP core implemented using Qt's Model-View framework Standards compliance is a design goal On-demand message list and body part loading Offline IMAP support Support for bandwidth-saving mode aimed at mobile users with expensive connection IMAP over SSH -- in addition to usual SSL/TLS connections, the server could be accessed via SSH Safe and robust dealing with HTML mail
